Imagine a city where the mayor tries to fix traffic jams by building a new highway.
But the new road attracts more cars, leading to even worse congestion.
This is an example of government failure – when a policy intended to improve the market actually makes things worse.
Key Point: Government failure occurs when the costs of intervention exceed the benefits, or when the intervention creates new problems that outweigh the original issue.
• Market Failure: Potholes form because drivers don’t pay enough for road maintenance.
• Government Intervention: The city imposes a toll to fund repairs.
• Possible Failure: The toll is too high, so drivers avoid the city, reducing traffic flow and causing more accidents elsewhere.
Result: The solution creates new problems.
Exam Question Example: “Explain what is meant by government failure and give two examples where a government intervention might lead to a less efficient outcome than the market.”
• Start with a definition.
• Provide two concrete examples (e.g., price controls, subsidies).
• Discuss the unintended consequences and why they reduce efficiency.
| Policy | Intended Benefit | Possible Failure |
|---|---|---|
| Subsidy for renewable energy | Encourage green technology | Distorts market prices → over‑production, waste of resources |
| Price ceiling on rent | Make housing affordable | Creates housing shortages, black markets |
Government failure reminds us that intervention is a double‑edged sword.
When designing policies, economists must weigh the benefits against the risks of creating new inefficiencies.
A well‑thought‑out policy, backed by accurate data and careful implementation, can correct market failures without turning into a new problem.
